Description
The Johnson Controls VA9104-GGA-3S is a high-performance, non-spring return direct coupled ball valve actuator engineered for precise proportional control in commercial HVAC and building automation applications. Designed for seamless integration with modern building management systems, this actuator delivers reliable, repeatable positioning across a wide range of hydronic and fluid control systems.
Key Features
- 24Vac supply voltage for compatibility with standard commercial control systems
- Multiple control signal inputs: 0–10Vdc, 2–10Vdc, and 4–20mA (with integrated 500-ohm resistor) for maximum system flexibility
- Proportional control for accurate, modulating valve positioning
- 35 lb-in (4 Nm) torque output — sufficient for a broad range of ball valve sizes
- 60-second full travel time for smooth, controlled actuation
- Non-spring return design maintains last position on power loss
- Direct coupled mounting eliminates the need for additional linkage hardware
- Manual override handle allows valve positioning during commissioning or power outages
- Screw terminal wiring connections for fast, secure field installation
Control Signal Compatibility
- 0–10Vdc proportional input
- 2–10Vdc proportional input
- 4–20mA proportional input (500-ohm resistor included)
Electrical Specifications
- Supply Voltage: 24Vac
- Torque: 35 lb-in
- Travel Time: 60 seconds (full stroke)
- Wiring: Screw terminals
Design & Installation
The VA9104-GGA-3S features a direct coupled design that mounts directly to compatible ball valves without the need for couplers or linkage kits, reducing installation time and potential points of failure. The integrated manual override handle is an essential feature for system commissioning and emergency operation, allowing technicians to manually position the valve without electrical power.
Applications
- Hydronic heating and cooling systems
- Chilled water and hot water coil control
- Building automation and energy management systems
- Variable flow hydronic distribution
- Commercial HVAC air handling units
